Thinking about moving to Hawaii? Or maybe you’re just curious what happens if a spouse cheats there. Either way, you’re about to learn something most people get wrong.
Adultery sounds like a crime from an old movie, right? In Hawaii, the answer is more interesting than you’d think. Stick with me, because this one has a twist.
What Is Adultery Under the Law?
Adultery means having sex with someone who isn’t your spouse while you’re still married. Simple enough, right?
Some states still treat this as a crime. Others only care about it in divorce court. Hawaii falls into its own category, and it’s not what most people expect.
Honestly, this is the part most people miss. Hawaii does not charge you with a crime for cheating. But that doesn’t mean cheating has zero legal consequences here. Keep reading, because it gets more complicated.
Basic Adultery Laws in Hawaii
Is Adultery a Crime in Hawaii?
Here’s the short answer: no. Hawaii rewrote its entire criminal code back in 1972. That new code, called the Hawaii Penal Code, took effect in 1973.
When lawmakers built this new code, they left adultery off the list of crimes. So today, you can’t be arrested or fined by the state just for having an affair.
Wondering if this applies to everyone in Hawaii? Not quite. Stay with me here, because there’s an exception coming up.
What About Divorce Court?
Hawaii is what’s called a “no-fault” divorce state. That’s a legal term, so let’s break it down. It means neither spouse has to prove the other one did something wrong to get divorced.
You just need to show the marriage is “irretrievably broken.” That’s a fancy way of saying it can’t be fixed. So simple!
But here’s a pattern interrupt for you. Even though Hawaii doesn’t require proof of fault, adultery can still come up. Courts sometimes look at it when deciding how to split property. It’s less common than in strict fault-based states, but it can still matter.
Advanced Adultery Rules You Should Know
The Homewrecker Lawsuit Still Exists
Wait, it gets better. Or worse, depending on how you look at it.
Hawaii is one of only a handful of states that still allows something called an “alienation of affection” lawsuit. This lets a spouse sue the third person, the one who had the affair with their husband or wife, for messing up the marriage.
You’re not alone if you’ve never heard of this. Most states banned these lawsuits decades ago. Hawaii, along with places like North Carolina, Mississippi, New Mexico, South Dakota, and Utah, kept the door open.
To win this kind of case, the spouse has to prove real love existed in the marriage. They also have to show the other person’s actions destroyed that love on purpose. That’s a high bar, honestly. Courts don’t hand out wins easily here.
There’s also a related claim called “criminal conversation.” Despite the scary name, it’s not a criminal charge. It’s actually a civil lawsuit too, and it’s about proving the affair partner had sex with your spouse. Confused about the difference? Alienation of affection focuses on lost love. Criminal conversation focuses on the physical act itself.
Military Members Face Different Rules
Here’s where things get serious. If you or your spouse serves in the U.S. military and lives in Hawaii, different rules apply.
Under the Uniform Code of Military Justice, adultery can still be treated as an offense. This applies no matter which state you’re stationed in, including Hawaii. Military prosecutors usually only pursue these cases when the affair also involves things like fraternization or affects unit discipline.
Think of it like this. Civilian life gives you a pass on the criminal side. Military life doesn’t always work the same way.
Penalties and Consequences
Let’s talk about what actually happens if adultery becomes an issue in Hawaii. Since it’s not a crime here, you won’t face fines or jail time from the state for cheating itself.
But civil consequences are real. If a spouse successfully sues for alienation of affection, the damages can be significant. In other states with similar laws, courts have awarded amounts ranging from a few thousand dollars to well over a million in extreme cases.
Divorce consequences are usually softer here. Because Hawaii doesn’t require fault, adultery rarely swings the whole case. It might influence how a judge views the marital estate split, but it’s not a guaranteed penalty.
Think of it like a parking ticket compared to a court summons. One is minor and mostly ignored. The other can actually cost you money and time in front of a judge.
Special Circumstances Worth Knowing
Some situations change how these rules apply. A friend once told me they assumed cheating always affects custody decisions. Turns out, that’s mostly a myth in Hawaii.
Hawaii courts focus on the best interest of the child when deciding custody. An affair alone usually isn’t enough to change custody outcomes. Judges care more about parenting ability, safety, and stability.
Personally, I think this approach makes sense. Punishing a parent’s dating life doesn’t always reflect their ability to raise a kid. But I get why some people disagree with that.
Another special case involves prenuptial or postnuptial agreements. Some couples add “infidelity clauses” to these contracts. These clauses can require a cheating spouse to pay extra money or give up certain assets if adultery happens. Hawaii courts generally enforce these agreements if they’re written clearly and signed voluntarily.
How to Protect Yourself Legally
Wondering what you should actually do if this situation applies to you? Let’s break it down step by step.
If you suspect your spouse is cheating and you’re considering divorce, talk to a family law attorney first. They can tell you whether Hawaii’s no-fault rules affect your specific situation. This part can be tricky, honestly, so don’t guess on your own.
If you’re thinking about an alienation of affection lawsuit, understand it’s a tough case to win. Courts want solid proof, not just suspicion. Gather documentation like messages, timelines, or witness accounts before filing anything.
If you’re in the military, check in with a military legal assistance office. They understand how UCMJ rules interact with Hawaii’s civilian laws. This combination confuses a lot of people, so don’t be embarrassed to ask questions.
And if you’re just trying to protect your own interests going into a marriage, consider a prenuptial agreement. It’s not the most romantic conversation, but it can save major headaches later.
What This Means for Everyday Couples
Most people in Hawaii will never deal with a courtroom over an affair. Enforcement of anything related to adultery is rare, and that’s true nationwide too.
Still, knowing your rights matters. You’re not alone if this whole topic feels confusing. Family law often mixes old traditions with modern rules, and Hawaii is a great example of that mix.
Now here’s a mini-story for you. A couple I read about years ago tried to sue under alienation of affection in Hawaii. The case dragged on for months. In the end, the damages awarded were modest compared to the legal fees spent getting there. That’s often how these cases go.
Frequently Asked Questions

Final Thoughts
So here’s the deal. Hawaii won’t arrest you for cheating, but it’s not a total free pass either. Civil lawsuits, divorce considerations, and military rules can all still come into play.
Most people will never face any of this directly. But if you’re navigating a messy breakup or a military marriage, it’s worth understanding where you stand. Stay informed, stay safe, and when in doubt, talk to a real attorney who knows Hawaii family law.
